APAJf-IATUS FOR CLOSING BOTTLES BY MEANS OF METAL CAPSULES.

Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed May 28, 1904 Serial No, 209,404.

To all whom it may concern: v

Be it known that I, EWALD GoL'rs'rEIN, engineer, a subject of the Kingof Prussia, German Em eror, residing at 111 Lothringerstrasse, ologne;Kingdom of Prussia, Empire of Germany, have invented certain new anduseful Improvements in Apparatus for Closing Bottles by Means of MetalCapsules, of whichthe following is a specification.

This invention relates to an apparatus or mechanism for applying metalcapsules to bottles and the hke; and the object of the same is toovercome numerousdisadvanta es f t 's incident to ap aratuses andmachines 0 t e as hereto ore constructed.

arious machines have been organized for applying ca sules to the necksof bottles, both interna ly and externally. In the class of machineswherein the capsule or closing device is inserted in the bottle-neck acomparatively high pressure is exerted by the punching means on adirect-acting yielding element cooperating with the capsule. Thispressure is so great that ordinarily many of the usual and otherwisepreferable washer materials cannot be employed in connection with thecapsule by reason of their fragility and inca ability to Withstand thishigh pressure. T e transmission of this hi h pressure to the bottle neckand'head mayie avoided if, the support or bearing counteracting thepressure e not held against the bottlemouth, but against a frame servingas a bottle-support or against .a base-rest, as the washer must alwayshave some pressure exerted thereagainst. To properly apply it to thebottle head or neck, an orgamzation of elements or a device is necessaryby means of which the bottle ma be pressed up against the washer by asuitably-regulated force. In other words, two forces differing in extentmust be brought into play with res ect to the bottle to whichthe capsuleis to be applied and the latter, and in the present apparatus these twoopposing forces are produced by a single a plication of power in suchmanner that both forces may be brought into the correct pro ortion' toone another as regards .of such height as tion positioned relativelythereto. Fig. 3 illustrates a complete machine, partly in elevation andartly in section.

Similar dharacters of reference are em ployed to indicate correspondingparts in the several views.

The frame T of the apparatus may be of any suitable material anddimensions and of such shape as to accommodate the application theretoof the mechanism, which will be hereinafter more particularly specified.This frame is supported by a suita e base and is to be convenient forcontrol by an operator. The up er part of the frame has a head orsupport 1 which is suitably chambered 0r recessed and is formed with adepending lip T surroundin a mouth T to receive the u per terminal or'ead of a bottleneck. In t e lower part of the frame a treadle orfoot-power lever D is movably held on a fulcrum-pin or analogous deviceH and at its freeterminal is provided with a properly-extendedcpressure-surface D. A

ottle support or i stern A vertically movable in guldes A, forming partof or secured to the frame at different elevations and both above thetreadle D. In the lower extremity of the stem A a pulley C is mounted,and in the rear'lower portion of the frame at a distance from the stem Aand said pulley C a guidepulley M is held in one posltion with respectto the frame. A plunger W is also movably held by the frame and anintermediate stopcollar or analo ous device W between which and a guidevi, through which the plunger has vertical posed and surrounds theplunger to serve as a cushion means. The lower extremity W of the pluner is enlar ed and carries ulleys N and L, tie pulley being in the owerextremity of said extremity W and of less diameter than the pulley N.The pulleys C, L, and M are a proximatel of the same diameter; but, asefore noted the. ulley M has a fixed position of rotation w ereas thepulleys C, N, and L are shifted vertically. A belt, cord, chain, orother analogous device K is terminally attached to an eye J at anintermediate point on the treadle D and from said eye passes over thepulley L downwardly under the pulley M, then u over the ulley N, anddown under the pu ey C and lists its opposite terminal fixed to theframe, as 0 early shown. The upper end of the plunsk A has a dependingmovement, a spring W is interengaging the said ger W? is connected tothe rear end of a; ressure-lever U, having its front end engag-- mg afulcrum V. a

The chamber or recess T in the headT andwith which the mouthcommunicates contains the mechanism directly cooperating with the casule and washer and the upper. end or head of the bottle-neck, e lowerterminal of the lip T is regularly rounded into the mouth T and the saidmouth is of less diameter thanthe chamber T, and bythis means a lowerannular shoulder T is formed adj acent'to the mouth. On the shoulder T"is disposed anannular elastic pressure element or gasket G, havi-n mentor coincide with the inner reduced portion of the said mouth. Thelowerordepending extremity of the headT is preferably formed as aseparate cup T, as clearly shown by Fig. 2, and removably secured to there-- maining part of the head by external screw threads at its upperend,the latterbeing inserted in a seat T in the head T. This cup T is easilyremovable and applicable tothe neck T and provides for the easydisposition of the several devices carried by the head the latter andthe ready replacement of said parts when found necessary;

Fixed in the cup T" is a brid B; and attached to the latter and de a inginto-the lower portion of the charm I T is a fixedstam or abutment S,having a lower concave seat S I This fixed stamp orpunch has its lowerterminal below theupper edgeof the elastic compression element orgasketG, and ulpper edge of=- the elementor gasket is a d'isp aceable tubularstem or punch R, having opposite slots 13* to permit operation of thesaid stain orpuneh with respect to the bridge B; e dlsplaceable tubularstem or punch R projects-upwardly and the head thereof is alwaysincontactwith an intermediate portion of the pressure-lever U. It will beobserved that thecom ressible element or gasket G lies embedded tweenfixed lower and outer walls and partially by an inner wall through-themedium' of the dependence of the fixed stamp or abutment S, andconsequentl when the displaceable stamp or punch is forced down it'causes the lower inner portion of the compressible element or gasket tobeforced inwardly and regularly bend the lower edge of the capsuleroperly around the bottle-neck and over-the head or mouth of the latter.

The bottle to be cap .is placed'on the disk or support A, an gradualdownward pressure is applied to the treadle D. This gradual downwardpressure is exerted throu h the beltj cord, chain, or analo ous deviceover the pulleys M, N, L, an O, and owing to the fixed position of thepulley M the stem A to which the disk orsupportA is secured is graduallyelevated and the bottle-neck disuch normal thickness that its inner sidewi 1 be in vertical slime Bil 264$ rected toward the moutliT Theresistance of the sprin W is such that the'elevating movement-o thebottle to be capped through the operation just described does not affect,zthe normal position of the pulleys N and L, as shown b F 1g. 3, but assoon as the mouth or head on of the bottle-neck entersthe mouth T andcontinues u wardly a ainst the washer D and the caps e E, which atterparts will be preliminarily disposed in proper posisure-lever U is alsooperated and exertsa grad-- ual downwardpmssure. on thedisplaceablestamp orpunch and at the same time the bottle is pushed upfirmly, and theupperhead or mouth end of the neclr F, as shownby Fig. 2,and the top bead F" Will be disposed fully the mouth T and thelowerextremity of the chamber T, the edge or rim of the capsule dependingoveror covering the bead F Hence the inward-expanding-pnes sure exertedagainst: the compressing element or gasket G b the operation. of-th'estamp or punch R wil bend the rim of the'capsule ownwardly over the beadF.

If the resistance in the spring or analogous device amounts to onehundred kilogram aecording to the pulley arrangement, the. pull on thecordmay rise to twenty-fivekilograms before a niovement'of the ver U iseffected.- H the position of the point- 1 of pressure of the said leverbe selected: rvelse tively to the point of rotation of the fulcnzm- Vandthe oint of connection Q in. such a way that-U V V 1 :5the pressureexerted onthe displaceable Ench'orstamp R amounts to five (4- z- Vograms, z expressing the tensions of the cord,- chain, .or analogousdevice 1K in kilograms. The pressure of the-bottle a so the pressure onthe washer D, amounts,-

on the other hand, only to two 2 kilograms.

In order to fix a capsule of twenty-eight millimeters diameter,atension, for instance, in the cord, chain, or analogousdeviee K ofabout one hundred kilograms is necessary. The

bottle is then operated with a pressure of about two hundred kil ramsagainst thefixed stampor abutment S, w lo the pressure transpressure'leagainst the stamp or abutment S, and thus mitted to the displaceablepunch R and servi'ng to compress the element or gasket G amounts tofifteen hundred kilograms.
